  • the flat band knitted fabric used according to the invention Due to the band textile structure used in the cooling unit packing provided in the cooling unit, a large surface area can be made available for the moisture of the air flowing against the flat band knitted fabric to be separated off thereon. Despite the large surface area, the flat band knitted fabric used according to the invention has a relatively small volume. This results in a large surface-to-volume ratio of the surface band knitted fabric. This makes it possible to maximize the surface area of the water volume to be cooled when wetting the flat band knitted fabric forming a contact surface.

In these areas of lower density, an advantageous flow of the counterflowing air in the cooling unit is possible through the surface textile. An increase in the extraction energy of the exhaust air can thus be avoided.
